Journal ArticleDOI
Archaea predominate among ammonia-oxidizing prokaryotes in soils
Sven Leininger,Tim Urich,Michael Schloter,Lorenz Schwark,Ji Qi,Graeme W. Nicol,James I. Prosser,Stephan C. Schuster,Christa Schleper +8 more
TL;DR: It is shown that archaeal ammonia oxidizers are more abundant in soils than their well-known bacterial counterparts, and crenarchaeota may be the most abundant ammonia-oxidizing organisms in soil ecosystems on Earth.
Journal ArticleDOI
The influence of soil pH on the diversity, abundance and transcriptional activity of ammonia oxidizing archaea and bacteria
TL;DR: Findings suggest that different bacterial and archaeal ammonia oxidizer phylotypes are selected in soils of different pH and that these differences in community structure and abundances are reflected in different contributions to ammonia oxidation activity.
Journal ArticleDOI
Complex archaea that bridge the gap between prokaryotes and eukaryotes
Anja Spang,Jimmy H. Saw,Steffen Leth Jørgensen,Katarzyna Zaremba-Niedzwiedzka,Joran Martijn,Anders E. Lind,Roel van Eijk,Christa Schleper,Christa Schleper,Lionel Guy,Lionel Guy,Thijs J. G. Ettema +11 more
TL;DR: The discovery of ‘Lokiarchaeota’ is described, a novel candidate archaeal phylum which forms a monophyletic group with eukaryotes in phylogenomic analyses, and whose genomes encode an expanded repertoire of eUKaryotic signature proteins that are suggestive of sophisticated membrane remodelling capabilities.
Journal ArticleDOI
Novel genes for nitrite reductase and Amo-related proteins indicate a role of uncultivated mesophilic crenarchaeota in nitrogen cycling.
Alexander H. Treusch,Sven Leininger,Arnulf Kletzin,Stephan C. Schuster,Hans-Peter Klenk,Christa Schleper +5 more
TL;DR: These findings suggest that mesophilic terrestrial and marine crenarchaeota might be capable of ammonia oxidation under aerobic and potentially also under anaerobic conditions.
Journal ArticleDOI
Nitrososphaera viennensis, an ammonia oxidizing archaeon from soil
Maria Tourna,Michaela Stieglmeier,Anja Spang,Martin Könneke,Arno Schintlmeister,Tim Urich,Marion Engel,Michael Schloter,Michael Wagner,Andreas Richter,Christa Schleper +10 more
TL;DR: The cultivation and isolation of an AOA from soil is described, showing it grows on ammonia or urea as an energy source and is capable of using higher ammonia concentrations than the marine isolate, Nitrosopumilus maritimus.
